“My 2023 Ioniq 6 is not charging as it has for 3 years. When charging to 100% my app States 347 and 382 miles. It should be 361 as stated by Hyundai. What happens if I drive under 45 mph after 5 miles the miles goes down to 303. It is not working as stated. It is not holding miles properly.”
NHTSA complaint #11742584, filed 2026-06“The ICCU on my 2023 Hyundai Ioniq 6 failed on December 5, 2025 after 19,616 miles. Luckily, the car was parked in my driveway when this occurred. If the car was in motion when the ICCU failure occurred it would have been very dangerous. The car cannot be driven. The car's system shows Hyundai Diagnostic Trouble Code (DTC) P1A906. The problem has been confirmed by a dealer. A new ICCU has been ordered. The car is under warranty and the dealer provided a loaner car while my car is being repaired.”
NHTSA complaint #11703829, filed 2025-12“March 21st at around 7:30 PM, I was driving on the highway when my panoramic sunroof suddenly exploded—or shattered—completely out of nowhere. It was a clear night, no rain or debris, and there were no cars directly in front of me. Nothing hit it—no rocks, no objects—just a loud bang, and the glass was gone. I’ve got photos of the damage (attached), and it’s clear this wasn’t caused by an external impact. The glass blew outward, which makes me think it’s a manufacturing defect or stress in the material. Thankfully, no one was hurt, but this is a major safety issue.”
NHTSA complaint #11649911, filed 2025-03“The ioniq 6 horn is a two (2) tone horn. First, one (1) of the tones went out (lower tone). Now, the horn completely doesn't work. Reading online, this is a common issue with the 2023 & 2024 ioniq 6. This is the same horn (car is the same platform) as the ioniq 5, and lots of forums online also have people posting about their horns going out and not working at all.”
NHTSA complaint #11639560, filed 2025-01“Horn progressively not working. 2 components:high and low frequencies have died and the horn is kaput. Forty still under warranty in my case but seriously concerned for security while driving as this is sudden and unexpected!”
